measure.
180°
Answer from: cynthiauzoma367
The measure of the missing angle x is:
m∠x = 100°Step-by-step explanation:
Let 'x' be the missing angle of a Pentagon
Given that the sum of four angles in a pentagon is 440°.
We know that:
The sum of internal angles in a simple pentagon is 540°.Thus,
we get the equation such as:
sum of four angles + x = 540°
440° + x = 540° ∵ sum of four angles = 440°
subtract 440° from both sides
440° + x - 440° = 540° - 440°
x = 100°
Therefore, the measure of the missing angle x is:
m∠x = 100°Answer from: Quest

(i really need ) read the story problem, and then answer the questions that follow. gordon works for a graphic design firm and is creating a label for a food truck vendor. the vendor specializes in finger food and wants to sell food in right conical containers so that they are easy for people to hold. to complete his label, gordon needs to collect several different measurements to ensure that the label he designs will fit the surface of the container. gordon has been told that the containers have a diameter of 4 inches and a height of 6 inches. part a: find the slant height of the cone. the slant height is the distance from the apex, or tip, to the base along the cone’s lateral surface. show your work. part b: find the measure of the angle formed between the base of the cone and a line segment that represents the slant height. part c: imagine two line segments where each represents a slant height of the cone. the segments are on opposite sides of the cone and meet at the apex. find the measurement of the angle formed between the line segments.
